PRINTING-PRESS.

Specification forming part of Letters Patent. No.43,383, dated July 5,1864.

To all whom it may concern.-

Be it known that I, FRANKLIN L. BAILEY, of Boston, in the county ofSuffolk, in the State of Massachuesetts, have invented and made certainnew and valuable Improvements in Printing-Presses; and I do declare thefollowing to be a .full, clear, and exact description of the same,reference being had to the accompanying drawings, which compose a partofthis speeltication, and to the letters of reference marked thereon, inwhich it will be found that- Figure 1 is a side elevation of this press.Fig. Sis a longitudinal vertical section taken through the center of theplaten and bed. Fig. 3 is a plane view of the press. Figs. 4 and 7 aredetached views of the platen-slide and its suppol't','being an obverseand reverse view of the two parts as they are related. Fig. 5 is areversed detached view of the ink-distributing tables, showing themethod adopted for the lateral mm ement of the distributing slides ortables. Fig. 6 is adetached view of the parts which are immediatelyinvolved in taking the impression, and it shows the impression as taken.

Toena-ble those skilled in the art to construct and operate myinvention, and that I may make known the number and nature of myimprovements, I will describe the .con struction of this press from thedrawings, the same letters referring to corresponding parts in theseveral figures.

A A are the two sides of the press. D is the base. 0 is a stationarybeam attached to the sides. E isa girt, also connecting the sides, allof which, being bound together, constitute a rigid frame, to which allthe moving parts are attached. To the beam 0 is fixed the plate 1,adjustable by the impressionscrews Z Z 2% to and from the beam in alohgitudinal direction,,or toward or from the bed F, for the purpose ofregulating the. impression uponthe platen G and its slide H, which arealso carried by this beam. The slide H has a vertical movement, as seenby comparing Figs. 2 and o.

G isa vibrating platen hinged to the slide H at G, which vibrates awayfrom and upward 5 from and downward to the plate 11, as seen i incomparing Figs. 2 and (i. This vibrating platen, besides its vibratingmovement, partakes of thesliding vertical movementof the i said slide1], when, by contact of the moving bed F against the slide, it. isforced dowuward to take theimpression, as seen'in Fig. 6.

F is a rotating reci 'iroeating bed (of peerliar construction, for thepurposes which will hereinafter appear) hinged. at l to the frame of thepress, and is made to swing in the arcota circle to and from the platenG, as seen in Figs. 2 and 6, for the purpose of taking the impression,as seen in Fig. 0, and inking the form of type, as seen in Fig. 2, alsoto allow the platen to be vibrated upward into a position convenient forplacing the sheet to be printed, or for its removal alter it is printed,as seen in Fig. 2. The movement of the bed 1: controls the vibratingmovements of the platen G by means of the camgroovc Q, extended from thelower side oi-lhe said bed, and the roller U, fixed to the neck G of thelower side of the platen (l, the said roller lit, ting into andfollowing the groove through all the movements of the bed. Thiscam-groove is so constructed that it will swing the platen upward andkeep it for a while stationary, while the bed is still moving outward tohave its form inked by the ink rollers it It 1%, as seen in Fig.2, andthis cam-groove is also so constructed that it will make the platenswing downward and quite to the slide I[,in advance of the arrival ofthe surface of the bed or form T, which presses ugainstit, as seen inFig. 6, by the combined movement of the downward Sliding motion oftheplaten and its support H, and the forward sweeping motion of the bed.

Upon the slide H, on a linewith the lower edge of the form, is fixed astep, 5, Fig. 6, and in range with it, on the bed, is fixed the invertedstep 4, which strikes upon the firstnamed step and makes the slide IIand platen G to partake of as much downward motion as will make theplaten and bed make perfect register when they come together.

In a cavity made halt in slide ii. and half in the stationary plate 1 isplaced a vertical spiral spring, Y, which keeps the slide lland platen Gin the position in Fig. 2, when not pressed downward by the steps on thebed F, as seen in Fig. (3. This spring stands on the stationary step \Von plate, I, and presses upward against. the step X on slide ii. Theslide If is kept in its place-in relation to the plate I by means of thescrews 2 2, Figs. 7

and 4, which pass through the grooves2 2 into the slide Hi The said'grooves allow the screws to partake of the vertical movement of the saidslide. The bed F is made to rotate and reciprocate, or sweep in and out,by means of the crank connections L L, the wrists t ton the c:a'nk N,and the wheel M, which are fixed to the ,continuousl y-rcvolving shaft0, which shaft and wheel, &c., are driven by means of the crank-handle tt.

The platen Gris made to carry some nippers or a nipper, a, fixed to thetwo uprights a a, which are themselves fixed to the rod 0, Figs. 2 and3, which is their center of motion. The nipper a is made to clasp thesheet of paper (lonll against the platen and pull the paper from thetype after the impression and lift again at the proper time and place,that the operator may remove the sheet from the platen. The nipper a.has-.upon it a lip, 1), Figs. 2 and 3, so arranged-that when thenipper-bar itself rests against the. surface of the platen this lipwill-project'upw'ard from the bar and off a suflicicnt distance from theplaten to allowthe margin of any card that is to be printed to enterunderit and by this lip to be pulled from the type after'the impression,at which time the bar and its lip are iai e.l from the platen a distancesufficient to a.l )W the card to drop into areceptacle below.

The movements of the nipper and frame are given by means ofthe' crankprojection d, rod c, the vibrating lever fl, which lever is operated byits 1oller g beating against the cam h, (fix d on the main shaft 0.0fthe press,) by means of the spiral spring j and fulcrum t'. The cam ILis so shaped that the nipperu is made to dropupon the platen G beforethe platen commences to swing downward to the impression, and the nipperis made by it to lift from the platen to allow the card to drop when theplaten is in a vertical position, or 11(3411) so, as represented in Fig,6. A part of the wheel .M and side A'in Fig. 1 are cut away, so thatthese movements may be better seen.

- The ink-rollers R R R are made to rise and fall in the grooves r r r,to rest upon and roll upon bearers 1 l 1 1 at the ends of the bed F, inrange with and of the same height as the type T by means of the bearers8 8, &c., on the rollers, so by means of these bearers and those. on thebed the rolls may always roll against the form in a proper manner, toink it well, without regard to the sweeping and unequal motion ofdifierent parts of the same bed. When the bed sweeps forward to take theim-' pression, theink-tablesKKarebrought underneath and against therollers It B it, to give them their supply of ink for the succeedingimpression. The upper surfaces of the slides K K together make the arcof a circle the center of which is that of the motion of the b'.-d F.-These slides K K have a lateral reciprocating motion alternately inopposite directions with respect to one another, and also to theirsupport J. The purpose of the lateral together.

movement is for the lateral distribution of the ink, and the object ofthe meeting and passing movement of the one in relation to the otherslide is that the ink may be the more completely broken up and crossedand lapped and transferred from end to end, and also "cry rapidly."

The apparatus for giving lateral movement to the tables isseen in Figs.5 and 1. The slides or tables K K hold studs S- S, which pass throughthe grooves S S in their support J into the forked ends of a leverhinged at p. This lever is madeto vibrate, and with it the slides ortables, by means of the rod n, crankwrist m on the ratchet-wheel m,which is made to rotate, and the tables to slide one tooth at eachrevolution of the press, by means of the spring finger-lever k, hingedat k on the side of the bed, and going back and forth with it,

which lever, at its lower end, toes into the space between thestationary studsl lon the frame of the press, alternately against" oneand then against the other, moving the ratchet forward one tooth andthen receding into the next tooth, so continuing the movement oftheratchet-wheel and the sliding of the slides or theink-tables. The slidesK K are kept in their place on support'J by means of the screws q g,which pass through the slots q q into the plates K K, as seen in Fig. 5.

The parts of thepress being described, I will nowdescribe the operationof the whole A sheet ofpaper being placed on the platen, motion is givento the wheel M and shaft 0 by its crank-handle. The bed is drawntowardthe wheel until the platen closes down and the bed against it'andthe impression taken. The ink-rollers now, will roll upon theink-tableto take their fresh supply of ink, when, by the continuedrotation of the wheel. and shaft 0, the bed is again pushed back and theplaten again raised and the rollers again roll over the type, thenippers lift from the platen, and the ink-tables are now moved, readyfor the next en trance of the rollers upon them. I

One feature of my invention is seen in the peculiar construction of thebed, which is so made that it allows the face of the type to sweep upagainst the faceof the platen without requiring the said platen to rockand tilt in order to be successfully approached by the bed and allowingthe platen to passively receive the impression. on its face asit slides.downward, Without rocking and tilting to ward the bed to give theimpression, as is the case in those presses where the center of mo-.tion of their beds is at right angles to some point in the form of typeand the edges of whose forms or beds describe a larger circle than theircenters; also, by so inclining the face of the bed no more machinery isrequired to ink the type than to place the rollers in stationary slots.The bed, with its face so inclined, is an exact compromise (so to speak)between the demands of the inking apparatus and the-demands of theimpression apparatus,

not rock or twist or vibrate or and this form of bed will allow the bedand the platen at the impression to come so nearly in line with theconnecting-rods that a great part of the strain will come upon them, tothe greater durability of the press and saving of iron and weight in itsconstruction;

and I am also enabled to make a rigid,simple,'

and strong thing of of iron only.

Another-part of my invention is the employment of a platen whichvibrates upward on a. hinge at its top edge, or nearly so. This platen,when down against its support at the time of the impression, is so heldthat it canmove in any way, so as to cause slurriug of the impressionalso, a part of my invention is in the locking this platen and the bedtogether, so that the one may intermit while the other can go on in entinued motion.

Another part of my invention is found in the "giving to the platen andits supports a vertical motion, (or an impression motion, so to speak,)and combining the same with the sweeping or rotatingreciprocating bedfor the purpose of impression by means of the steps or any equivalentmeans; and also the means of regulating the impression through all theseparts; also in the arrangement of the nipper and its controllingappendages.

Another part of my invention is the method of inking by means of two ormore lateral distributing-tables moving in opposite directions, so, bymeans of the rollers, to counteract the inequalities in the thickness ofthe ink and make it even the sooner; also, the means employed foroperating these tables.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. A rotating reciprocating or sweeping bed, F, whose flat plane surfacefor the type stands in a plane always obliquely to its center ofmotion-and obliquely to the arc of a the bed, being one piece circlewhich any point on its surface may describe as the bed moves to and froon its center i or centers of motion, so that the lower edge of I anyform will scribe a smaller circle than any other part of the same. 2. Avibrating platen, which is .so arranged that its face swings upward forthe reception of the sheets upon a hinge nearitstop edge;- also, thecombination of the same with the bed F; also, the giving the same adownward-sliding or equivalent motion, for the purpose specified.

3. The combination of the platen with its movable support or slide H;also, the combination of the spring Y or its equivalent with the slideH.

4. Giving the platen its vibrating move ments and period of restby-means of the cam-groove Q or its equivalent, and the moving bed F.

5. The combination of the platen and a movable support, H, or itsequivalent, with the ad-- jusita-ble support-plate I, for the purposespecifie 6. The combination of the nipper a and its lip Z) with theplaten, which swings upward to receive upon it the card to be printed.

7. The arrangement for operating the nipper a with its lip, for thepurpose of dropping the cards.

8. The combination of two or more sliding ink-distributing tables,moving laterally and going in opposite directions to one another,substantially as described; also, the combination with them of theratchet'wheel m and forked lever p, which operate them.

9. Combining with a rotating reciprocating led an -ink-distributingtable, which moves laterally, for the purpose described.
